| 目的探讨能量CT标准化碘浓度(NIC)对直肠癌淋巴结转移的预测价值。 方法前瞻性分析42例直肠癌患者的临床资料,根据术后区域最大淋巴结病理结果分为淋巴结转移阳性组与阴性组,利用后处理站测量最大淋巴结短径和NIC。比较两组淋巴结短径、NIC值。采用单因素和多因素Logistic回归分析预测淋巴结转移的影响因素。ROC分析淋巴结短径和NIC对直肠癌淋巴结转移的预测价值。 结果两组淋巴结T分期、动脉期NIC、短径比较,差异均有显著性(P＜0.05)。淋巴结动脉期NIC、短径为直肠癌淋巴结转移的影响因素。ROC结果显示,动脉期NIC诊断效能与淋巴结短径相似,而联合诊断效能显著大于单独指标诊断效能。 结论能量CT NIC对直肠癌区域淋巴结转移有一定的预测价值。 |

| AimTo explore the predictive value of energy CT normalized iodine concentration (NIC) for lymph node metastasis in rectal cancer. MethodsThe clinical data of 42 rectal cancer patients were prospectively analyzed and divided into lymph node metastasis-positive and negative groups according to the pathological results of the largest lymph node in the postoperative region, and the short diameter of the largest lymph node and the NIC were measured by using a post-processing station. The lymph node short diameters and NIC values were compared between the two groups. Single-factor and multifactorial Logistic regression analyses were used to predict the influencing factors of lymph node metastasis. ROC analysis was performed to analyze the predictive value of lymph node short diameter and NIC for lymph node metastasis in rectal cancer. ResultsThere were significant differences in lymph node T staging, arterial phase NIC, and short diameter between the two groups (P＜0.05). The NIC and short diameter during the arterial phase of lymph nodes were influencing factors for lymph node metastasis in rectal cancer. ROC results showed that the diagnostic efficacy of arterial phase NIC was similar to that of lymph node short diameter, while the diagnostic efficacy of combined diagnosis was significantly greater than that of individual indicators. ConclusionThe NIC of energy CT has certain predictive value for regional lymph node metastasis in rectal cancer. |
